CSP notation has been used extensively for teaching and applying concurrency theory, ever since the publication of the text Communicating Sequential Processes by C.A.R. Hoare in 1985. Both a programming language and a specification language, the theory of CSP helps users to understand concurrent systems, and to decide whether a program meets its specification. As a member of the family of process algebras, the concepts of communication and interaction are presented in an algebraic style. An invaluable reference on the state of the art in CSP, Understanding Concurrent Systems also serves as a comprehensive introduction to the field, in addition to providing material for a number of more advanced courses. A first point of reference for anyone wanting to use CSP or learn about its theory, the book also introduces other views of concurrency, using CSP to model and explain these. The text is fully integrated with CSP-based tools such as FDR, and describes how to create new tools based on FDR. Most of the book relies on no theoretical background other than a basic knowledge of sets and sequences. Sophisticated mathematical arguments are avoided whenever possible. Topics and features: presents a comprehensive introduction to CSP; discusses the latest advances in CSP, covering topics of operational semantics, denotational models, finite observation models and infinite-behaviour models, and algebraic semantics; explores the practical application of CSP, including timed modelling, discrete modelling, parameterised verifications and the state explosion problem, and advanced topics in the use of FDR; examines the ability of CSP to describe and enable reasoning about parallel systems modelled in other paradigms; covers a broad variety of concurrent systems, including combinatorial, timed, priority-based, mobile, shared variable, statecharts, buffered and asynchronous systems; contains exercises and case studies to support the text; supplies further tools and information at the associated website: http://www.comlab.ox.ac.uk/ucs/. From undergraduate students of computer science in need of an introduction to the area, to researchers and practitioners desiring a more in-depth understanding of theory and practice of concurrent systems, this broad-ranging text/reference is essential reading for anyone interested in Hoare’s CSP.
Bino Phillips has seen his share of crime-fighting, but nothing has prepared him for the desperate search for a serial killer stalking the streets of Dallas—a serial killer that has more than the usual thirst for blood. One woman has been found, the blood sucked from her body. She and a friend, who remains missing, were to be key witnesses in Bino's defense of a young coed dealer. Now Bino finds himself in a sudden race against death, especially when the killer gets personal and targets Bino's secretary as his next victim. Used to be you could call the Feds for help. But for some reason even they're stumped by this clever would-be Dracula.
The Battle of Jettena Junction is a remarkable work. This intriguing combination of fiction work and history textbook subverts and reverses the expectations of historical fiction, using plot as the backdrop for history rather than history as the backdrop for plot—a history book with a dash of fiction rather than a fiction book with a dash of history.
Lackey Ferguson met Marissa Hardin once, the morning he signed on to build a bathhouse at the Hardins' fancy Fort Worth home. But when Marissa is found brutally murdered, Lackey becomes the number one suspect in a trumped-up case, while a sexual psychopath runs loose. Desperate to find the real killer, Lackey must evade arrest while keeping an eye on his fianc├®e—who may just be the killer's next target.
In this spine-chilling courtroom drama, beautiful thirtysomething defense attorney Sharon Hays takes on the case of Midge Rathermore, the teenage daughter of a Texas millionaire, who is accused of hiring a hit man to kill her father. In addition to her case, Sharon finds herself and her daughter being stalked by a savage sexual psychopath.
HLA Hart's The Concept of Law is one of the most influential works of philosophy of the twentieth century, redefining the field of legal philosophy and introducing generations of students to philosophical reflection on the nature of law. Since its publication in 1961 an industry of academic research and debate has grown up around the book, disputing, refining, and developing Hart's work. Under the sheer volume of competing interpretations of the book the original contexts - cultural and intellectual - that shaped Hart's project can be obscured. In this book, renowned legal historian AWB Simpson attempts to sweep aside the volumes of academic criticism and return to 'Troy I', revealing the world of post-war Oxford that produced Hart and his famous book. Drawing on his personal experience of studying and teaching in Oxford at the time Hart developed The Concept of Law, Simpson recreates with characteristic wit the social and intellectual culture of Oxford philosophy and the law faculty in the 1950s. He traces Hart's early work and influences, within and outside Oxford, showing how Hart developed his picture of philosophy and its potential for enriching the understanding of law. He also lays bare the painful shortcomings of post-war Oxford academia, depicting a world of eccentric dons and intellectual Cyclopses - isolated and closed to broad, interdisciplinary exchange - arguing that Hart did not escape from the limitations of his intellectual world. Simpson's entertaining, and controversial, account of the world that produced The Concept of Law will be essential reading for all those engaged in interpreting and teaching the seminal book, and an engaging read for anyone interested in the history of Oxford philosophy and legal education.
An Introduction to Design for Civil Engineers is a concise book that provides the reader with the necessary background on terminology used in design. With this book as a guide, entry-level students of civil engineering will better understand from the outset lectures on detailed subject areas. Drawing on a wealth of experience, the authors present a
In this suspenseful thriller set in Dallas, A. W. Gray takes us behind the police lines of a homicide investigation and into the private passions that fuel an urban nightmare. A stolen BMW is recovered with a stash of cocaine, lurid photos, and a charred, dismembered body. Dallas Metro detective Ham Benno soon connects the victim to a secret circle of family depravity and sexual indiscretion—a mother and daughter who blur the lines between predator and prey. Are the suspects innocent targets? Guilty avengers? Nothing has ever been proven, and a stone-cold killer is about to strike again.

Abstract: "We present a mathematical model which is the most abstract allowing (i) a fully compositional semantics for timed CSP and (ii) a natural abstraction map into the standard failures/divergences model of untimed CSP. We discuss in detail the construction and properties of this model, and explore the variety of nondeterministic behaviour it encompasses. We argue that, at least in some sense, this model is definitive for timed CSP.
Its proof relies on an algebraic argument based on partial orders, which may well have applications outside databases, for example in the field of 'true concurrency'. We indicate how the algorithm can be generalised to a number of other network topologies, and give guidelines for further generalisations. If combined with timestamping, the algorithms provide highly concurrent methods of ensuring that the sequence of updates executed at all nodes corresponds to the order implied by these timestamps.
